Alonso denies he will walk out on McLaren

Shanghai, China - Fernando Alonso is not ready to swap his recalcitrant McLaren for a supermarket trolley just yet, despite the Formula One team's troubled start to the season prompting speculation about whether the Spaniard will see out the year.

The former double world champion and McLaren endured a frustrating season opening race in Australia, following on from pre-season testing marred by a lack of power and reliability from their Honda engines.

Alonso, despite putting in what he called one of the best drives of his career, could only battle for the lower points positions, before dropping out of contention altogether and eventually retiring.

His team-mate Stoffel Vandoorne could only finish 13th and last, after being lapped twice by Sebastian Vettel's race-winning Ferrari.

That McLaren felt the result exceeded expectations was a sign of how deep in the doldrums the sport's second most successful team is.

McLaren's form renewed speculation about whether the 35-year-old, in the final year of a three-season deal, would stick around.

Former driver and Alonso's close friend Mark Webber also cast doubt on his future in comments to Belgian media.

"Definitely not true," Alonso told reporters ahead of this weekend's Chinese Grand Prix. "I prefer to be here than to be in the supermarket in my home town.

"I keep competing because I want to have more trophies," he said. "I am in Formula One, I'm delivering at my best, I'm more prepared than ever, I'm performing at my best."

Troubled reunion

McLaren, which last won a race in 2012, went into the season expecting to make a big step up the order after a season of progress following a troubled reunion with engine supplier Honda in 2015.

But the Japanese manufacturer's continued struggles with the V6 turbo-hybrid formula have left McLaren, which finished sixth overall in 2016 after ending 2015 ninth, mired near the bottom of the pecking order.

The team expects to struggle even more this weekend in Shanghai and Alonso's plight has not gone unnoticed. Former McLaren team mate and rival Lewis Hamilton, in particular, has expressed a desire to see him in more competitive machinery.

When asked if he could switch teams next season, perhaps even moving up to Mercedes alongside Hamilton, Alonso didn't rule it out.

"I have nothing to say right now, it's a question for the future," he said, adding: "Nothing is ruled out in life."
